Why in the world would you lock up a Lab in a cage? THey are great family dogs. I have two and they don't loose the hunting instinct by becoming part of the family. Dogs are social pack animals. Locking them up in solitary confinement is cruel, and you friend shoud not have a dog under those circumstances. Why in the hell have a dog if you are going to chain it to a tree outback or keep it in cage?
